This article makes sense and offers good tips.
You can bet the next time I rent something, especially a car, I'll take pictures and send them to my computer in case theres a dispute later.
How much time or money would it cost to take pics of all 4 sides? Most cameras have the option of time/date stamping the pictures. Imagine going to court and saying "Judge heres pics of the vehicle condition when I took possession of it and when I returned it" could the rental car company produce the same? Not likely.
Sadly we live in a world where you must take prcautions to protect yourself in everything you say and do.
I probably would've gotten a better response from the last rental car fiasco I had if I'd a been smart enough to take pictures and send them to their corporate office.
Instead I got an email 5 mos later telling me "we understand how you felt but heres some coupons to use with your next rental from us". Yea right, that'll never happen again.
